5 Claims.

The present invention relates to at knitted fashioned hosiery, more particularly to the manufacture of so-called non-run stockings, and .has for one of its main objects the provision of a .f5- stocking wherein the entire leg and foot, including the heel, sole, and toe sections, consist of fashioned non-run-knitted fabric, thereby producing a stocking of characteristic structure having a lacy appearance and anti-ravelling? construction throughout.

It is an important object of the invention to provide a non-run stocking wherein the heel, sole, and toe sections are all made of non-run stitches to correspond to the non-run stitches in the leg and instep portions of the stocldng.

The invention also aims to provide a non-run.

stocking consisting of a stocking fabric blank hav- ,ing its leg, instep, heel, sole, and toe portions constructed entirely of non-run stitches, the 2o selvedges of said blank being fashioned on the knitting machine, whereby the stocking, when looped and seamed, will conform to the human leg and foot.

The invention is moreover characterized by the 25 particular manner of working the heel, sole, and

toe sections of non-run stitch construction, whereby to impart to said sections a shape for the adequate fitting of the stocking foot.

Other important objects and advantages of the invention will be in part obvious and in part pointed out hereinafter.

In order that the invention audits mode of operation may be readily understood by those skilled in the art, I have, in the accompanying drawings'and in the detailed description based thereupon, set out a possible embodiment of the invention.

In these drawings:

Figure 1 is a side elevation of a stocking made in accordance with the invention and diagrammatically illustrating a possible construction thereof'.v

Figure 2 is a face elevation diagrammatically showing the construction of the leg blank used in making the stocking shown in Figure 1.

Figure 3 is a face elevation diagrammatically representing the construction of the foot blank and its connection to the corresponding portion so of the leg blank in the manufacturing of the stocking.

Figure 4 is a greatly enlarged diagrammatic representation showing the knitted structure of a fashioned portion of the foot fabric.

-Figure 5 is a diasrammaticview of the outline (Cl. (i6-178) of the foot portion of the blank explaining the mode of making the same.

Having more particular reference to the drawings, wherein likee characters of reference will designate corresponding parts throughout, I have i5 shown in Figure 1 a complete stocking I0 constructed in accordance with the invention. The stocking, as represented in Figure 1, is of the socalled non-run construction and is made of a leg blank I2 (Figure 2) with which is' knitted a foot flo blank I4 (Figure 3).

- From Figure 2 it will appear that the leg fabric blank I2 consists of a welt I6, leg proper I8, high splice heel sections 20, and heel tabs 22, each'heel tab terminating with the usual ravelling topping l5 extension 24.

The foot fabric blank I4 interknitted with the leg blank I2, as illustrated in Figure 3, comprises the instep 26, sole sections 28, and toe 30, the latter having the ordinary topping extension 32.

-The leg and foot blanks are knitted on yordinary full-fashioned knitting machines provided with well known loop lspreading attachments, for instance, such as shown and described in the patent to Gastrich, No. 1,998,364, dated April 16, 25 1935, and operating to form courses of plain loops, and thereafter spread and interlock selected loops with associated plain loops to prevent the formation of runs.

In knitting the stocking, the leg blank I2 is 30 started at the welt on a flat full-fashioned knitting machine, as is customarily done in the art, by feeding the yarn to the needles over the entire length of the needle bar. Preferably, although not necessarily, the welt I6 is knitted plain, that 1.35

is, without the spreading of loops, so that said welt will have the usual elasticity.

Following the completion of the welt, the leg proper is knitted, the knitting machine being set so that the loop spreading attachment thereof 40 will function to spread and interlock certain loops with adjoining plain loops, thereby forming an anti-run fabric throughout the entireleg portion. The machine is moreover set so that at the proper time in the process of the leg knitting, the feedl'45 ing of the yarn is controlled in such a manner that a number of loops will be dropped at each end of a course, thereby reducing the width of the blank for fashioning the same.

'Ihis type of knitting is continued through to 50 the end ofthe heel tabs 22, a reinforced yarn being introduced,.as is customary, for the formation of the high splice heel sections 20 and heel tabs 22. Therefore, it will be understood that according to the present invention and contrary 55 struction.

of course, it will be appreciated that the lowerpart of each heel tab 20 must be so fashioned as vto impart thereto the required rounding of the heel in order that the same may adequately conform to the human foot. For-that purpose, and in accordance with the invention, the feeding of the yarns to the knitting needles is such that starting at approximately the point indicated at P in Figure 2, two loops at the outer selvedge of each heel tab 2li are dropped every first course of consecutive series of courses. In practice, it is found that by dropping two loops at the end of a course every fifth course, a sumcient abrupt reduction in the width of the fabric is had to produce a selvedge 34 of the required slant to assure proper formation of the heel pocket.

After the completion of the heel tabs 22, several plain ravelling courses are knitted to constitute the topping extensions 24 serving to facilitate the handling for the final looping operation in the manner well understood in the art.

The finished leg blank I2 may then be transferred to the foot knitting machine by engaging the lower marginal edge 36 of the leg blank and the inner selvedges 38 of the heel tabs with the bank of needles of said foot knitting machine. In this manner, the foot I4 is knitted by feeding the proper yarns back and forth over the needles to form the instep 26 as a continuation of the leg, the sole sections 28 as continuations of the heel tabs 22, and finally the toe 30, terminating the foot blank.

During the operation of the machine for the formation of the foot I4, the loop spreading attachment functions to spread and interlock the selected loops so that the entire blank, including the sole sections and toe, is constructed completely of non-run stitches. Itis to be noted that the high heel sections 20, heel tabs 22, and toe 30 are reinforced to a greater extent than the sole sections 28.

Attention is particularly called to the fashioning of the foot blank which constitutes one of the major characteristics of this invention. Upon reference to diagrammatic Figure 5, it will appear that at the beginning of the foot blank I4, a series of courses, approximately thirteen in number, are knitted on the entire set of needles to form a straight selvedge portion A. Thereafter, two loops at the end of a course are dropped every other course for a series of approximately twenty-five courses, thereby gradually reducing the width of the fabric for shaping the beginning of the sole as indicated by portion B. Subsequently, there are formed the necessary number of courses to provide the desired foot length, as represented by portion C, after which two loops are again dropped at the end of a course every fth course in a series of approximately twentyfive courses, thereby fashioning the end of the sole, as indicated by slanting selvedge portion D.

Following the completion of said portion D, the toe fabric is knitted. The particular fashioning of the toe fabric to impart thereto the proper tting is had as follows: With the beginning of the'toe fabric, two loops are dropped at the end of a. course every second and fifth courses alternatively for approximately ninety-one courses. thereby producing an inclined selvedge portion E extending at an angle with respect to the slanting selvedge portion D. Thereafter, two

loops are dropped at the end of a course every second course for approximately thirty-two courses, thus decreasing the width of the fabric and forming the tapering selvedge portion F extending at `an angle relatively to the inclined selvedge portion E. Accordingly, it will be understood that the opposite selvedges of the toe fabric constitute broken lines converging towards the end of said toe fabric and therefore the necessary rounding of the toe is obtained to properly shape the same. The toe fabric is preferably terminated with several plain ravelling courses constituting the usual topping extension 32.

Upon completion of the lnterknitted leg and foot blanks, the same may be looped, seamed,

dyed, and finished in the manner customary in 'I'he dropping of the loops in the manner stated to fashion the stocking fabric may be obtained through actuation of a narrowing head of the knitting machine, which functions to govern the distance travelled by the carrier rods in their yarn laying movements. The function of said narrowing head, for the4 purpose specified, may be controlled by the usual pattern chain mechanism through a particular arrangement of control buttons predisposed, according to a definite pattern, for attaining the gradual reduction in the width of the stockingfabric at those points along the length thereof as hereinbefore indicated.

In Figure 4, there is diagrammatically shown the knitted structure of a fashioned portion of the foot fabric. From said Figure 4, it will be noted that the fabric, as produced, comprises plain courses 40 and interlocking courses 42 which preferably alternate with each other. It is, however, to be understood that any number of plain courses may succeed each other and any number of interlocking courses may be successively formed, or that every course may be an interlocking course, if found desirable.

As represented in the drawings, the plain courses 40 are formed from plain loops 44, while the interlocking courses 42 consist of alternate plain loops 46 and spread interlocking loops 48. In producing the interlockingloops, a course of plain loops is first formed, and then selected loops, that is, every alternate loop, is spread from the Wale in which it originates into an 'adjacent Wale, thus interlocking the loops together to prevent ravelling thereof. Asalso represented, the dropping of loops for the purpose of shaping the stocking fabric blank is preferably done in an interlocking course 42 so that the end loops 44a of a preceding plain course 40 will lock the associated plain and spread loops 46 and 48 respectively interknitted therewith, in order to retain them in overlapping, interlocking relation until gathered in the rear seam.

From the foregoing, it will be appreciated that I have provided a flat knitted fashioned stocking having a non-run construction throughout. `I am aware that flat knitted stockings having a leg fabric` and instep fabric constructed of antiravelling stitches have been made heretofore. However, I believe I am the first to provide a stocking, the leg and foot portions of which, including heel, sole, and toe sections, entirely conconsisting of approximately thirty-two courses lwith two stitches dropped at the-end of every -courses to give the desired lengthfto the blank,

each course extending the 'full width of the last course of said second portion; the fourth portion consisting of a predeterminedA number of courses with stitches dropped at the end of every fifth course; the fifth portion consisting of a predetermined number of courses with stitches dropped at the end of every s'econd and fifth courses alternatively; and the sixth portion consisting of a predetermined number of courses with stitches dropped at the end of every other course.

2. A at knitted fashioned non-run stocking comprising a leg and foot, both entirely cornposed of non-run knitted fabric, said foot comprising six consecutively knitted portionsf the first portion consisting of approximately thirteen courses, each course extending the full width of the blank; the second portion consisting of approximately twenty-ve courses with two stitches dropped at the end of every second course; the

third portion consisting of a predetermined num ber of courses, each extending the full width of the last course of said second portion; the fourth portion consisting of approximately twenty-five courses with two stitches dropped at the end of every fth course; the fifth portion consisting of approximately ninety-one courses with two stitches dropped at the end of every second and. fth courses alternatively;'and the sixth portion other course.
